Yeah, I know. It's been asked a million times, but here goes once again. I'm wondering if I should get better mileage in my extremely stock 74 Duster with the 225 auto and Holley 1945 stock carb. Timing is factory 0.0 TDC. Everything stock under the hood and in the drive train. I get 14.5 in the city and 16.5 on the highway. Is this normal? Or too low? BTW, I put the car on a chassis dyno and got 79 rear wheel horsepower form this 50K mile motor. Thoughts?
